CHARLES H. MOORE, OF NEW YORK, N. Y.

WATER-CLOSET OUTLET CONNECTION.-

To all whom it may concern:

Be it known that I, CHARLES H. MOORE, a citizen of the United States,residing in New York city, in the county of New York and State of NewYork, have invented a new and useful Improvement in VVater- ClosetOutlet Connections, of which the following is a specification.

The object of this invention is to provide an earthenware water closetconstructed at the base and outlet end, so that in conjunction with agrooved metal floor plate that connects to the soil pipe and a greasesoaked gasket, a trap is formed that will provide a perfect seal againstthe inflow of sewer gas notwithstanding any slight movement of thecloset after it is installed. To accomplish this, I form a groove in thefloorplate by two imperforate flanges, one of them extending up from theouter edge of the floor-plate and one of them extending up from theinner edge of the floor-plate, and in this groove I place an oil orgrease soaked compressible gasket; that grease enough is pressed fromwhen the closet is bolted to the floor-plate to surround and submergethe lower end of the depending ring and form an independent grease sealat each side of the said ring and between it and the flanges of thefloor-plate, and a communication is made from the space between theinner flange of the floor-plate and the ring 3, to the discharge pipe ofthe closet so that whenever the closet is flushed the space referred tobetween the inner flange of the floor plate and the ring 3 if not filledwith grease will at once be filled with water. thereby assuring atrapped and sewer gas tight joint at the end of the discharge limb underall conditions.

In the accompanying drawings forming a part of this specification,Figure 1 represents a central vertical section of the inventionconnected to a leaden soil pipe. Fig. 2 is a plan view of the under sideof the device. Fig. 3 represents a modification of the device connectedto an iron soil pipe. Fig. t shows the flange soldered to a pipeprojecting above the floor line.

1 represents the discharge end of an earthenware water closet having oneor more holes through the base at each side for bolts to enter andengage with a metal floor plate to secure the closet to the soil pipe.

2 is a circumferential groove formed in the Specification of LettersPatent.

to fit in the recess 5 and forms the inner,

flange of the floor-plate 9 and the inner wall of the groove 10. a

9 shows a floor-plate that fits on the thimble 6 and is solderedthereto, and in conjunction with the upper end of the said thimble thatextends into the closet, forms a groove 10 for the depending ring 3 toenter and form a trap. This floor-plate 9 rests upon the offset in thethimble 6 and covers the solder joint that connectsit to the thimble,therefore the said solder oint is not exposed to any gases from thesewer pipe. The groove 10 is made deep enough to admit the dependingring 3 to enter it some distance in compressing the gasket, so there isquite a space between the two flanges of the floorplate that forms thegroove and the sides of e the depending ring 8 that is filled withgrease pressed from the gasket when the closet is made rigid to thefloor-plate.

12 represents two or more lugs that are made on the outside of theflange of the 13 represents a soft gasket saturated with grease oil orsome suitable liquid substance that is pressed from the gasket when thecloset 1s screwed in place, and W111 flow lnto the space between theflanges of the groove 10 and the depending ring 3 andmake a liquid sealindependent of the compressed gasket joint.

14 represents the bolts and 15 is the floor.

In place of the gasket, any suitable sub,,

stance that will yield to slight pressure and not get hard can be used.

9 represents a depending threaded end of the floor-plate 9 and isintended to be used when iron or threaded metal soil pipe'is,

used up to the floor line. In Fig. 4: the leaden or other metal sectionof soil pipe is extended through the floor 15 and floor-plate 9 andforms the inner flange of the said floor plate 9.

The advantages are first: tour seals are provided within the groove ofthe floor-plate against the inflow of sewer gas so that perfeet securityis maintained under all conditions. Second: the solder joint isprotected so that sewer gas will not altect it. Third: the gasket ispreserved by the grease that covers it and cannot become brittle orrotten, and will keep the gasket saturated.

Having described my invention, what I claim as new and desire to secureby Letters Patent, is-
